Throughout their 'By Request' tour, Metallica have posted videos of show performances along with behind the scenes footage. The latest clips are from Prague (watch above), Vienna and Warsaw (watch below).

The band played Prague, Czech Republic, on July 8. The video from that gig shows the band warming up in the tuning room, including guitarist Kirk Hammett pretending to be outraged that the fans didn't pick 'Ride the Lightning' to play at that show. Performances of 'Orion' and 'St. Anger' from the concert are also shown, followed by a couple minutes of the band rehearsing 'Unforgiven 2.'

The video of the July 9 Vienna, Austria, concert features drummer Lars Ulrich talking with a fan at a pre-show meet and greet. Metallica's performance of 'Master of Puppets' and 'Whiskey in the Jar' round out the clip.

More meet-and-greet footage is shown on the video from the July 11 show in Warsaw, Poland. This time Ulrich, Hammett and bassist Rob Trujillo are hanging out with fans. That's followed by some tuning room jamming of the new song 'Lords of Summer' and the concert performances of 'For Whom the Bell Tolls' and 'The Call of Ktulu.'

After Metallica played in Europe for most of the summer, North American fans will have a chance to see the band at the Heavy Montreal festival on Aug. 9.
